commit5833112df7upstream. Reflink should force the log out to disk if the filesystem was mounted with wsync, the same as most other operations in xfs. [Note: XFS_MOUNT_WSYNC is set when the admin mounts the filesystem with either the 'wsync' or 'sync' mount options, which effectively means that we're classifying reflink/dedupe as IO operations and making them synchronous when required.] Fixes:3fc9f5e409("xfs: remove xfs_reflink_remap_range") Signed-off-by: Christoph Hellwig <hch@lst.de> Reviewed-by: Brian Foster <bfoster@redhat.com> [darrick: add more to the changelog] Reviewed-by: Darrick J.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
